Node.js Crash course #4 Requests & Response
Node. js is a Javascript run-time environment built on Chrome's V8 Javascript engine. It comes with a http module that provides a set of functions and classes for building a HTTP server. For this basic HTTP server, we will also be using file system, path and url, all of which are native Node.
The Node. js Client API enables you to create Node. js applications that can read, write, and query documents and semantic data in a MarkLogic database.
Request and Response object both are the callback function parameters and are used for Express. js and Node. js. You can get the request query, params, body, headers, and cookies. It can overwrite any value or anything there.
